Back in the days of Raymond Berry, the Pats wore their whites at home every game I think. Berry thought they looked better than the reds. (And for that era, I think I agree.)
Other than that, the only time I can recall the Pats wearing white at home was a preseason game against Denver in 1997.
As for the silvers, I like how mine looks on me when I wear it, but on the players they didn't look good. Like they were wearing the whites and were sweating heavily.
